Description

  The present invention relates to a glass mold for producing a glass panel which is designed for an exterior surface of a building and curved in a multi-curved surface.

  In the prior art, it is known to bend a glass panel by gravity using a concavo-convex glass mold provided with undulating supports connected to each other by support rods arranged along a side surface.

  A glass mold for bending glass in two directions with a stationary lower load-bearing structure having individual supports mounted on parallel support beams is known from the patent specification of patent document 1. The upper edge of the support undulates in an uneven shape, and these are formed with a curved shaped surface fixed in two directions. Above, the lower support structure is installed on the upper load-bearing structure, which is movable in the vertical direction and comprises a plurality of rod-shaped bodies arranged in parallel and easily deformed during heating. The glass panel is curved by this glass mold: the selected support of the lower load-bearing structure is placed on the support frame; the upper load-bearing structure is placed on the upper part where the rod-shaped body forms a flat surface; the glass panel to be molded The glass mold is then heated; the upper load-bearing structure is simultaneously lowered to a lower position relative to the lower load-bearing structure to form the glass panel. In the lower position, due to the gravity of the glass panels, the rods of the upper load-bearing structure, and with it, the molded glass panel conforms to the shape of the supports of the lower load-bearing structure, and the upper edges of these supports Reflects the defined surface shape.

  Due to the use of an upper load-bearing structure consisting of rods, the glass mold according to this solution curves the glass panel except in the case of forming multi-curved panels with different cross-sectional profiles, which are highly desirable for architectural applications. The possibilities are limited. Furthermore, the glass mold has a complicated structure in which a plurality of parts are movable with respect to each other, and breakage or sticking occurs at a temperature at which the bending process is performed.

  The purpose of the present invention is to develop a glass mold that produces a curved glass panel with multiple curved surfaces. This glass mold has no restrictions and is dispersed in position, and the continuous curvature of the glass panel is changed. At the same time, the construction and operation of the glass mold are simple.

  According to the present invention, a glass mold for producing a curved glass panel having a curved surface comprises: an immovable lower load-bearing structure, which is defined in longitudinal, lateral and vertical directions. A support frame and a number of undulating supports placed on the support frame and arranged vertically and parallel to each other; a lower load-bearing structure, which supports the glass panel to be molded The lower load-bearing structure support is installed on the support, and the lower load-bearing structure support has a wavy upper edge, and the upper edge has a predetermined curved surface in the longitudinal and lateral directions of the lower load-bearing structure. It is arranged in an array that is formed by bending vertically up and down alternately in at least one direction, and its curved surface has various bends and depths; and upper load-bearing structure Body, which deforms under the influence of temperature A There plate, placed on the edge of the support supporting the molded glass panel for bending.

  The upper load-bearing structure may comprise an underlay glass panel.

  It is advantageous for the support frame to comprise a longitudinal beam with an upwardly projecting holding part suitable for maintaining the support in a predetermined vertical position.

  In the lower load bearing structure, it is further advantageous that the supports are spaced apart from one another by 1 to 3 cm.

  It is also advantageous for the support to be formed from a heat-resistant material, in particular ceramic.

  Glass molds for producing multi-curved glass panels ensure unique, repeatable and changeable glass panels, and the contours of such panels are planned in a predictable manner And can be manufactured. The glass mold can be easily adapted to the modified contour of the manufactured glass panel and also allows repeated regeneration of the same contour panel as required. The use of glass panels as the upper load-bearing structure makes it possible to use this underlaying panel for certain applications, such as building applications, or to ensure that materials can be recycled, melted and reused in glass blast furnaces. Become.

The perspective view of the glass type | mold for manufacturing the glass panel curved into the multi-curved surface is shown. FIG. 2 shows a side view of the glass mold of FIG. 1 as viewed from direction II of FIG. FIG. 3 shows a side view of the glass mold of FIG. 1 as viewed from direction III of FIG. FIG. 4 shows a perspective view of the lower load bearing structure of FIGS. A perspective view of a glass mold with a curved glass panel after completion of the forming process is shown and drawn with a portion of the upper load bearing structure removed for clarity.

  A glass mold 1 for manufacturing a multi-curved glass panel according to the present invention shown in FIGS. 1 to 4 includes an immovable lower load-bearing structure 2 in which a vertical direction 2a and a horizontal direction 2b are defined. The lower load-bearing structure 2 includes a support frame 4 and a undulated support body 5, and the support body 5 is movably installed on the support frame 4 that is vertical and parallel to each other and maintains a gap between the support bodies 5. . Since the support 5 can be detachably installed in the lower load-bearing structure 2, these supports 5 can be changed as necessary.

  The support frame 4 has a structure for reliably embedding a support 5 that can be fixed and removed within the frame. As shown in the figure, for example, the support frame 4 includes a vertical beam 4a including a holding portion 4b protruding upward, which is suitable for maintaining the support 5 in a predetermined vertical position.

  According to the present invention, the support 5 of the lower load-bearing structure 2 has a wave-shaped upper edge, and the support 5 has a predetermined curved surface in the longitudinal direction 2a and the lateral direction 2b of the lower load-bearing structure 2. In at least one direction, the vertical direction 2c is arranged in an array that is alternately bent up and down, and the curved surface has various bends and depths.

  Within the lower load-bearing structure 2, the supports 5 are spaced apart from each other by 1 to 3 cm depending on the thickness of the curved glass panel and the desired appearance of the final surface of the bent glass panel (surface shape complexity). Yes.

  The support 5 is made of a rigid heat resistant material, in particular ceramic.

  In the support 5 of the lower load-bearing structure 2, a flat upper load-bearing structure 3 is provided and used to support the curved glass panel 6. The upper load-bearing structure 3 is a plate that is easily deformed under the influence of temperature, and is preferably an underlay glass panel 3a.

  Prior to the bending of the glass panel, a glass mold is prepared by appropriately installing the support 5 formed in an undulating manner on the support frame 4 of the lower load-bearing structure 2 in a predetermined arrangement, and a curved surface having a desired shape Ensure acquisition of. The shape determination of the support 5 and its placement on the glass-type lower load-bearing structure 2 are carried out by a computerized method. The upper load-bearing structure 3 in the form of a plate, in particular an underlying glass panel 3a, is placed on a support 5 integrated with the lower load-bearing structure 2, and a glass panel 6 to be bent is placed on the underlying glass panel 3a. In order to easily separate the prepared glass panel 6 from the plate of the upper load-bearing structure 3, in particular from the underlay glass panel 3a, the upper load-bearing structure 3 is coated with a separating material such as known in the glass industry for example. .

The glass mold 1 is heated at a temperature of 550 to 750 ° C. together with the molded glass panel 6. As a result of the softening of the plate forming the upper load-bearing structure 3 and the glass panel 6 to be formed, and as a result of gravity, the plate and panel are surfaces defined by the upper edge of the support 5 of the lower load-bearing structure 2.
